aylor and Natsumi are making block towers out of large and small blocks. They are stacking the blocks on top of each other in a

frozen [14]

Answer:

The height of a large block is of 12.1 inches and of a small block is of 7.7 inches.

Step-by-step explanation:

This question is solved using a system of equations.

I am going to say that:

x i the height of a large block.

y is the height of a small block.

Taylor uses 4 large blocks and 2 small blocks to make a tower 63.8 inches tall.

This means that:

$4x + 2y = 63.8$

Simplifying by 2:

$2x + y = 31.9$

$y = 31.9 - 2x$

Natsumi uses 9 large blocks and 4 small blocks to make a tower 139.8 inches tall.

This means that:

$9x + 4y = 139.8$

Since $y = 31.9 - 2x$

$9x + 4(31.9 - 2x) = 139.8$

$9x + 127.6 - 8x = 139.8$

$x = 12.1$

$y = 31.9 - 2x = 31.9 - 2(12.1) = 7.7$

The height of a large block is of 12.1 inches and of a small block is of 7.7 inches.

Well it's hard to visually inspect this long text; let's look at it.

$\begin{matrix} \textrm{Secs} & \textrm{GroupR} & \textrm{GroupS} \\ 45 & 1 & 0 \\ 50 & 2 & 1 \\ 55 & 1 & 1 \\ 60 & 2 & 2 \\ 65 & 1 & 0\\ 70 & 1 & 2 \\ 75 & 1 & 0 \\ 80 & 1 & 1 \\ 85 & 1 & 0 \\ 90 & 2 & 2 \\ 95 & 1 & 1 \\ 100 & 2 & 1 \\ 105 & 1 & 1 \\ 110 & 2 & 2 \\ 115 & 1 & 1 \\ 120 & 2 & 1 \\ \end{matrix}$

Based on visual inspection the averages look about the same.

Find the value of 2.<br> 78°<br> 1200<br> 15°<br> B

andrew11 [14]

I tried but see if this helps you In algebra, it is easy to find the third value when two values are given. Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side.

Given ΔMNO, find the measure of ∠LMN.

Novay_Z [31]

Answer:

104°

Step-by-step explanation:

If segments NO and NM are congruent, then angles NMO and NOM are congruent. So, their supplements, angles NML and NOP are congruent. That is ...

∠NML ≅ ∠NOP = 104°

∠NML = 104°
